3. Customer Need
Centers for Medicare & Medicaid Services (CMS) – “In order to improve
the effectiveness of detecting and potentially preventing fraud, waste,
and abuse, CMS implemented the ArcGIS Platform as an additional BI
Tool.”
Anomalies & Outliers on the Map:
Referrals Made > 50% Change over Time Similar Providers
Isochrone Around Provider Travel Time of Service Stops
Providers by Specialty Code Closest Provider
Summarize Beneficiaries

4. Big Data
(OLAP)
Deployment Option
Hybrid & Disconnected
• ArcGIS Portal, ArcGIS Servers (federated, cluster), ArcGIS Server
(unfederated, stand-alone), ArcGIS DataStore, StreetMap Premium
• ArcGIS Online

5. Towards ATO
Project
• Planning & Design
• Workshops – Hardware & Requirements
• eXpedited Life Cycle (XLC) Process – Technical Review Board (TRB)
• Architecture Review (AR)
• Preliminary Design Review (PDR)
• Detail Design Review (DDR)
• Security Control Assessment (SCA)
• User Acceptance Test (UAT)
• Operational Readiness Review (ORR)

6. Challenges
Environmental
• Not Public-facing – No PII/PHI could leave to arcgis.com
• 3-Zone Architecture – For ArcGIS token, needed to negotiate SSL
handshakes and establish trust to route authentication between daisy-
chained servers
• Multi-VPN & Multi-NICs – Different networks for different groups
Project-specific
• HTTPS – Needed to decrypt
• No Web Adapter – Needed to proxy without
• Red Hat Enterprise Linux (RHEL) Version – Support
• ODBC Driver – Teradata

7. API Query “Find all Providers X miles from Y for these Beneficiaries”
Foreground Data
From Integrated Data
Repository (IDR)
Background Map
From ArcGIS –
Internal & External
Web Application
Map Sandwich
Managerial
• Transparent Communication
• Timely Escalation
Technical
• Infrastructure as a Service (IaaS) – Rapid piloting & prototyping in Amazon Web Services (AWS) as
AWS Partner – Takeaway Alert!
• Internal Basemaps – e.g. Aerial imagery from National Agriculture Imagery Program (NAIP), USDA
• Citrix – For ArcGIS Desktop
• Pass-through System Design
• Reverse Proxy

9. Lessons
• Advantages of ArcGIS
• COTS – Users & Roles, LDAP Integration, Security Model,
SDLC, etc.
• Raw Speed of Development – E.g Production-ready on-
premise on-the-fly drag-and-drop geocoding with a small team
in a few months
• Tight Peopleware Coordination – Esp. where
Horizontally Sliced Projects
